INSULATING MATERIALS WITH FORMED HOLES Russian patent published in 2016 - IPC H01B3/04 H01B7/02 

Abstract RU 2574070 C2

FIELD: electricity.

SUBSTANCE: improved electrically insulating tape (16) is offered which comprises the protective layer (20) and the electrically insulating layer (18) joined with the protective layer (20). At least, one of either the electrically insulating layer (18) or the protective layer (20) includes a set of formed apertures (26) to improve penetration of impregnating pitch into the insulating tape (16) during pitch impregnation.

EFFECT: invention provides optimum impregnation of the tape that improves the ability to resist to impact of voltage and premature breakdown and accident.

10 cl, 11 dwg
